TRANSPONDER MODE SELECTION

Mode selection can be automatic (Ground and Altitude Modes) or manual (Standby, ON, and Altitude Modes).
The STBY, ON , and ALT Softkeys can be accessed by pressing the XPDR Softkey.
Selecting a transponder mode:
1) Press the XPDR Softkey to display the Transponder Mode Selection Softkeys.
2) Press the desired softkey to activate the transponder mode.
GROUND MODE
Ground Mode is normally selected automatically when the aircraft is on the ground. The transponder
powers up in the last mode it was in when shut down. Ground Mode can be overridden by pressing any one
of the Mode Selection Softkeys. A green GND indication and transponder code appear in the mode field of
the Transponder Data Box. In Ground Mode, the transponder does not allow Mode A and Mode C replies,
but it does permit acquisition squitter and replies to discretely addressed Mode S interrogations.
When Standby Mode has been selected on the ground, the transponder can be returned to Ground Mode
by pressing the GND Softkey.
STANDBY MODE (MANUAL)
In Standby Mode, the IDENT function is inhibited.
NOTE:
Standby Mode can be selected at any time by pressing the STBY Softkey. In Standby, the transponder does
not reply to interrogations, but new codes can be entered. When Standby is selected, a white STBY indication
and transponder code appear in the mode field of the Transponder Data Box. In all other modes, these fields
appear in green.
